This function uses the discrete approximation of Boucher and Demery (2016) to fit a multi-state discrete character threshold model following Felsenstein (2012; Revell 2014).
fitThresh(tree, x, sequence=NULL, ...)
An object of class "fitThresh"
.
object of class "phylo"
.
a named vector.
assumed ordering of the discrete character state. If not supplied and then alphanumeric order is assumed.
optional arguments.
